Graco InvisiPac HM25 Hot Melt System Overview

Graco is revolutionizing bulk hot melt dispensing with its award winning InvisiPac line of bulk hot melt systems. The HM25 is a melt-on-demand system allowing users faster start up times, clog and char free dispensing along with the ability to use lower cost bulk hot melt. All of these benefits add up to huge savings over the life of the Invisipac HM25 system.

How the InvisPac System Works

The Invisipac HM25 uses an integrated vacuum system to bring hot melt to an in-line melter. Unlike traditional tanks that need to bring hot melt to temperature and remain melted for long periods of time, the Invisipac HM25 system brings hot melt to the melter on-demand so no char is ever created.
